Loss of power towing fifth wheel at elevation

[vic69]

I was towing my fifth wheel this weekend and experienced a loss of power
pulling a grade up Genesee for Coloradoan's and then at the Eisenhower tunnel. I pulled over and let the truck Idle and it seemed to clear up
but then it happened again Any Ideas?
Thanks

That just happened to my 05 f250. I lost all power going up a steep hill. I had to back down about 50’ with my 40’ toy hauler. I had to get a running start to make it up the hill. I brought the truck to the dealer. The dealer removed the air filter to look at the turbo vanes. All vanes are damaged. My truck is all stock. Dealer will not warranty turbo. They are unable to find what damaged the turbo. This is my 2nd turbo and only 28000 miles.

Yikes. Whatever damaged the vanes on your turbo must have also been sucked into your intake. No offense, but these turbos are absolutely horrendous, as im sure you can tell already.

if the truck cleared up after sitting at idle it doesnt sound like a turbo issue to me , id like toknow what it did after you took back off ,and did the check engine light ever come on

No check engine light and no codes. The truck acted normal and then
when I got to the tunnel approach about 11,000 feet it slowed down
This week I found some boost leaks and maintained them ,i"m going to
hook it back up and take it for a drive and see what happens

What I've heard is that ford rebuilt the front end. I could go as fast as i wanted with my 03 but when i started towing with my 06 i could only do 55 up hills. Pretty embarrassing if you ask me.
